5. GHI'UEIHRINI A TTORNEY Patented May 12, 1931 UNITED STATES PATENT OFFICE BENJAMIN GAMBARINI, OF ALAMEDA, CALIFORNIA FLYING MACHINE Application filed February 10, 1930. Serial No. 427,266.

moving through the air in a lateral direction and therefore one but also one which is capable of moving vertically.

A further object is to produce a device which is extremely simple in construction, which is economical to manufacture. v

A still further object is to provide means whereby in case of motor failure, the motor may be dropped so that the balance of the vel hicle will float to earth in a manner which will not injure the occupants.

Other objects and advantages will be apparent during the course of the following descrlption.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

' Figure I is a side elevation of my device, Figure II is a cross section, taken on the line 2-2 of Figure I, looking down on top of the device, and a Figure III is an enlarged tion showing the cabin.

The ordinary air vehicle is provided with supporting wings which support the vehicle though the fact that the same is traveling through the air at a speed sulficient to buoy the plane and as soon as this speed is lost, the

plan'e must descend. Applicant has produced a vehicle wherein a rotary screw is mounted above the cabin in such a way that it may be revolved thus lifting the entire device in a vertical direction and when it is desired to move in a horizontal direction the screw may detail cross secbe tipped into the direction it is desired to proceed or may be tipped to the right or left so" as to direct the vehicle from one side to the In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the-nu- ;"meral 5 designates a substantially cylindrical and by viewing Figure III it Will be noted that this floor is a substantial distance above the bottom line 9 of the housing which permits a removable bottom 11 to be held therein which removable bottom provides a motor room 12 within which, any suitable motor may be housed. This motor power is shown in the drawings at 13 which is adapted to drive a gear 14 which in turn meshes with the gear 16 carried upon the shaft 17. This shaft extends upwardly through the housing and has provided at its upper end a universal joint 18 carried within a bracket 19, which bracket is secured to the housing 5. A thrust bearing is shown at 21 which is secured to the shaft 17 and bears against the bracket 19.

A curved roof 22 serves to rotatably support a se ent 23 which is provided with a slot 24 t rough which the upper part 26 of the shaft extends. This shaft has secured thereto, a propeller 25. The shaft passes through a slider 27 which moves in the slot 24 and .serves to guide the shaft 26. In order to rotate the segment 23 I mount the same upon the roof 22 through the medium of an overlapping flange 28. In order to turn the segment I prefer to provide teeth 29 on the inner surface thereof, which in turn are meshed with a gear 31 which is rotated by a shaft 32 extending downwardly into the cabin and rotated through the medium of a hand-wheel 33. In order to move the shaft 26 in the slot 24 I provide a bell crank 34 which is pivoted as at 36, one end of the bell crank being connected as at 37 to the slider 27 and has its opposite end connected to a link 38 which is actuated by a hand lever 39 moving over a segment 41.

In order to prevent the cabin from, rotating due to the action of the propeller I provide a pair of struts 42 and 43 which carry a vane 44 the action of which is obvious. In order to retain the bottom 11 in position, spring pressed latches 46 are normally in position shown in Figure III but in case of emergency the link 47 may be pulled with the result that the cords 48 will pull the various latches out of engagement with the upturned sides of the bottom and as a consequence the bottom will drop away leaving the cabin and propeller relieved of the weight of the motor and as a consequence it will float to earth in a way which will not seriously injure any persons therein. In 'order to take up the shock of landing I provide aplurality of pivoted telescope legs 49 pivoted as at 51 and having springs 52 between the legs 49 and the cabin 5. It is of course understood that the telescoping .foot port-ion 53 is also spring 10 mounted. I

i It is to beunderstood that the form of my invention herewithshown and described is to j be taken as a preferred example of the same and that various changes relative to the material, size, shape and arran ementof parts may be resorted to without eparting from the spirit of the invention or the scope of the sub'oined claims. I f aving thus described my invention, I 2 claimze 1. In a device of the character described, a cabin, a rotary disc positioned on said cabin, a propeller shaft extending through said disc,- a propeller secured thereto, means for rotat- 25 ing said disc and means for tipping said propeller with respect to the center of said disc.

2. A vehicle of the character described, a cabin, a removable floor carried by said cabin, a motor positioned on said removable floor, 30 a shaft extending vertically through said cabin and adapted to be rotated by said motor, a universal joint positioned in said shaft, a propeller secured to said shaft at a point above said universal joint, means for tipping 35 said propeller out of axial alignment with the ortion of said shaft below said universal oint and means for rotating said tipping shaft about the axis of said cabm.

In testimony whereof I aflix-m signature. 4o BENJAMIN GA fiARINI.
